It is not ethical at all. These kinds of stories can have a negative impact on society. They can desensitize people to the seriousness of abduction and also promote a warped view of sex. In addition, it can make victims of real - life abduction feel retraumatized or violated just by the existence of such stories.
I'm not aware of many such stories in mainstream science fiction literature. Most science fiction focuses more on the scientific, psychological, and adventure aspects of alien abduction rather than the erotic element. However, in some very niche or underground works, there might be some inappropriate content like this, but it's not common or widely recognized in the general sci - fi community.
In general, the idea of combining alien abduction with an erotic theme is not a typical genre. Mainstream media usually keeps these two concepts separate. Alien abduction stories are often about scientific exploration gone wrong or the unknown in space, not about any form of sexual undertones. So it's quite rare to find such stories in the more well - known works.
One famous non - erotic abduction story is 'The Ransom of Red Chief' by O. Henry. It tells the humorous story of two men who kidnap a boy, but the boy turns out to be so much trouble that the kidnappers end up paying the boy's father to take him back. Another is 'Taken' which is a movie about a father's desperate search for his abducted daughter. It focuses on the action and the father - daughter relationship rather than any inappropriate content.
In general, science fiction literature is more about exploring the unknown, the implications of extraterrestrial life, and the human experience in the face of the alien. When it comes to alien abduction stories, they often focus on the fear, the mystery, and the scientific aspects. The idea of adding 'erotic' elements to such stories is not in line with the main goals of most science fiction writing. There may be some fringe or underground works that play with this concept, but they are not widely recognized or part of the core of science fiction literature.
One way is through strict legislation. Laws can be put in place to ban the production and distribution of such content. For example, in many countries, any form of media that promotes non - consensual or unethical sexual content is illegal.
One major ethical issue is the objectification. It can objectify the idea of alien life forms in inappropriate ways. Also, it may mix sexual content with a concept that is often used in science - based or psychological exploration in a wrong way. This can be offensive to those who are interested in the more serious aspects of alien abduction theories.
One reason could be the target audience. Alien abduction stories usually attract fans of science fiction and horror, who may not be interested in an erotic element. Another is that it may be considered inappropriate or too strange to combine the two concepts.
